  2. Muscle cell - Wikipedia

    en.wikipedia.org/wiki/Muscle_cell

    [4] [5] Skeletal muscle cells and cardiac muscle cells both contain myofibrils and sarcomeres and form a striated muscle tissue. [6] Cardiac muscle cells form the cardiac muscle in the walls of the heart chambers, and have a single central nucleus. [7] Cardiac muscle cells are joined to neighboring cells by intercalated discs, and when joined ...

  3. Muscle - Wikipedia

    en.wikipedia.org/wiki/Muscle

    Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement. Among many other muscle proteins, present are two regulatory proteins, troponin and tropomyosin. [1] Muscle tissue varies with function and location in the body. In vertebrates, the three types are: skeletal, cardiac (both striated), and

  4. Smooth muscle - Wikipedia

    en.wikipedia.org/wiki/Smooth_muscle

    Smooth muscle-containing tissue needs to be stretched often, so elasticity is an important attribute of smooth muscle. Smooth muscle cells may secrete a complex extracellular matrix containing collagen (predominantly types I and III), elastin, glycoproteins, and proteoglycans. Smooth muscle also has specific elastin and collagen receptors to ...

  5. Muscular system - Wikipedia

    en.wikipedia.org/wiki/Muscular_system

    Three distinct types of muscle (L to R): Smooth (non-striated) muscle in internal organs, cardiac or heart muscle, and skeletal muscle. There are three distinct types of muscle: skeletal muscle, cardiac or heart muscle, and smooth (non-striated) muscle. Muscles provide strength, balance, posture, movement, and heat for the body to keep warm. [3]

  6. Human musculoskeletal system - Wikipedia

    en.wikipedia.org/wiki/Human_musculoskeletal_system

    The body contains three types of muscle tissue: (a) skeletal muscle, (b) smooth muscle, and (c) cardiac muscle. On the anterior and posterior views of the muscular system above, superficial muscles (those at the surface) are shown on the right side of the body while deep muscles (those underneath the superficial muscles) are shown on the left ...

  7. Composition of the human body - Wikipedia

    en.wikipedia.org/wiki/Composition_of_the_human_body

    In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal ...

  8. The Clitoris And The Body - The Huffington Post

    projects.huffingtonpost.com/projects/cliteracy/...

    From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.

  9. Striated muscle tissue - Wikipedia

    en.wikipedia.org/wiki/Striated_muscle_tissue

    The main function of striated muscle tissue is to create force and contract. These contractions in cardiac muscle will pump blood throughout the body. In skeletal muscle the contractions enable breathing, movement, and posture maintenance. [1] Contractions in cardiac muscle tissue are due to a myogenic response of the heart's pacemaker cells ...
